Less than 6 months old Onkyo Headphone Amp used lightly for Hi Res sound whilst gaming. It stayed on my desk all the time never took it out anywhere. Excellent little amp but I have 2 pcie sound cards now this is not needed.

From the Manufacturer: "The first practical and portable DAC/amp to provide a direct-digital connection to your iPod touch®, iPhone®, or iPad®, the DAC-HA200 brings high-resolution D/A conversion and premium Onkyo amplification to all the headphones in your collection. As well as connecting Lightning-equipped iOS devices, the USB-A input supports AOA 2.0-compliant Android devices for CD-quality sound, while a USB Micro-B input links to PC and Mac. When connected via USB, your DAC-HA200 offers free access to the Onkyo HD Player Pack app, allowing you to load your iOS device with 96/24 and 5.6 MHz DSD albums and to personalize the sound with a 16,384-band equalizer. The compact aluminum amp is loaded with proven technology, including a Burr-Brown PCM5102 D/A converter, MUSES 8920 op-amp, and a discrete Class AB push-pull output stage. As you would expect from a company that’s been handcrafting hi-fi equipment since 1946, audio performance is extraordinary—a vital, energetic, and engaging listen on headphones of any kind. In your pocket or on the desktop, the DAC-HA200 is a must-have for any music lover that’s serious about discovering how good a portable setup can sound".
